Application filed September To all whom it mag concern:

Be it knownthat lfNmLs ilniLsnN, a citizen of the UnitedStates,residing in the city of Pittsburg, in the; county of Contra Costa and State of California, have invented a new and useful Improvement in an Automatic Stamping Machine with Magazine, of which the following is ZI-SPGClfication.

My invention relates to improvements in marking devices adapted for attachment uponcan clinching machines and the like, for securing covers upon cans, whereby a characteristic mark may be made uponeach can to identify the contents thereof during subsequent operations ofa. ca'nni-ngprocess.

The. primary object of invention is to provide an improved marking device for marking cans during a canningprocess.

Another object is to provide an improved device which is attachable directly upon a reciprocating part-ofa can clinching machine and operates in conjunction therewith for marking each can. I

A further object is to provide an improved device which will accommodate a plurality Ofmarking elements identifying diifere'nt products. I I

Another 1 object is toprovide a device which will' facilitate the change ofmarking elements to correspond to a change in prodllCt. v

A further object is to provide an improved "device which will be continuous in action and which may be adjusted to c if ent products while the machine is in operation. A

A 'still further object istdprovide an inn proved device which is' simple in construction and efiicient in operation and which may be readily installed upon existing machines. I I

"I accomplishthese and other objects by means of'the device disclosed in the drawings forming apart of theprese-nt specification'where'in like characters of reference are" used to designate similar; parts throughout said specification and drawings and in which: k I

In the canning of vegetables and other products the goods to be canned after suitableprepa ation, are placed in cans which are thenfed through a machine, commonly termed a can clinching machine which operates to place and secure tops upon the filled cans. The cans are then passed through suitable cookers and subjected to the various steps of the canning process. The labeling of the cans does not occur until after the cans have been passed througha' number of distinct operations. I Asanumber of different characters ofigoods as well asvarions gradesof goods are commonly canned at thesame time it isflnec'essary that each can be marked with a distinctive mark identifying the contents prior to labeling. Heretofore thishas commonly been done manually, an employee being stationed near the clinching machine to mark each can with its distinctive mark as itleaves'the. machine. As cans are'fe'd through the machine at a rate of approXima-tely fortyper minute this marking is a laborious taskmequiringthe constant attention of the employee. My present invention is "therefore designed to avoidthis manual operation and to provide for the automatic marking of the'cans as they leave the clinching machine.

Referring to the drawings the numeral 1 is usedto designate ingeneral the-- frame of a can'clinching machine of the type used for clinching the tops upon square asparagus cans. As machines of'thisgeneral character are well known and form no .,part {of the present invention nodescription is herein necessary other than to state that cans-2, previously filled with the product to be canned, are moved intermittently, pastareciprocating member '3 upon which is carried one of aset of dies adapted to cl-inclrthe edges of a canand cover to secure-the cover upon the can and sealthe contents-injthe can. The cans 2 are' fed in spaced relation onto a conveyor not shown moving intermittently and timed to cause each can to be moved and held directly under the die while of the conveyor operating to move the sealed can from the machine and to move the succeeding can into position under the die.

My invention consists of a carrier 4 provided with a plurality of radi'ally disposed arms 5 having gripping elements 6 secured seasons run upon the machine.

upon the outer ends thereof. The carrier is rotatably mounted upon an eccentric hearing 7 carried by a sleeve 8 secured upon a shaft 9.' The shaft 9 is rotatably secured upon the top of the reciprocating member 3 by suitable blocks 11. A handle 12 1s secured upon the outer end of the shaft 5) whereby the shaft and eccentric bearing 7 may be rotated to elevate the carrier 4 for a purpose hereinafter more fully described. The shaft 9 extends outwardly over the end of the reciprocating member 3 and the carri'age 4 is positioned upon the shaft so as to be directly above the point at which each can 2 stops after leaving the machine while the reciprocatingv member descends to chnch the cover upon the succeeding can.

A marking element 13 is detachably secured upon the end of each arm 5 by means of the gripping elements 6, each marklng element being provided with a resilient st'amp 14 made of rubber or other suitable material and having raised figures 16 formed thereon to print a designating mark upon the cans 2. The figures 16 may be of any suitable character 'adapted to designate different kinds and grades of goods, at different figure or group of figuresbeing used to designate each different kind or grade of product. It is preferable to provide a sufficient number of arms .5 to' accommodate all the marking elements necessary for a particular The arms 5 are so spaced that only the lowermost marling element 13 will engage the cans2 moved thereunder, the carriage being adjustably secured in a desired position with the required marking element 1n operative position by means of a spring latch 17 engaging notches 20 formed around the edge of a ring 18 secured upon the hub 19 of the carrier.

The carrier is normally held in its opera tive position with respect to the shaft 9 by a spring latch 21 arranged to engagea notch 22 formed upon a ring 23 secured upon the outer end of the sleeve 8 the eccentric hearing 7 being swung to its extreme lower position.

The operative marking element is inked after each downward stroke by means of an inking pad 24 pivotally mounted upon a frame 26 secured upon a stationary portion p of the frame 1 of the clinching machine adjacent the carrier 4. The pad is actuated by links 27 pivotally connected to the ends of the pad and to rods 28 having their upper ends connected to the shaft 9 upon opposite adjustment of the pad relative thereto whereby the pad may be caused to engage the printing surface of the adjacent marking element 13 as shown in Fig. 3 when the carrier 4 and the rods 28 are moved upwardly, by the upward stroke of the reciprocating member 3. During the downward movement of the carriage, the inking pad is swung outwardly from the path of the marking element by means of the links 27 and rods 28, in this manner permitting the marking element to be moved into contact with a can 2 as shown in Fig. 4. A. spring 33 is secured upon the frame 26 and arranged to press against the back of one of the side members 32 to normally hold the pad well up against the marking element to insure an effective inking and to aflord' a slight resilience against the pressure imparted by the links 27 when the carrier is moved downwardly.

In operation, my invention is as follows. The device being attached upon the clinching machine as above described, the carrier is set to place thedesired marking element m operative position. When now the machine ls op'erated in its normal way the reciprocatlng member 3 of the machine will cause the entire carrier timed relation to the through the machine. is clinched upon each can by the'reciproeating member 3 and its associated dies, the succeeding movement of the can will bring it directly under the marking element so that the succeeding reciprocation will move the marking element against the can and cause a distinguishing mark to be imparted thereon. In this manner the cans are automatically marked for identification throughout subsequent operations in the canning process.

lVhen a change is made in the product being canned, the common practice is to place a block upon the conveyor by which the cans are moved. The block informs the operator of the clinching machine as to the nature of the new product and a short inter val is allowed during which no cans are fed to the machine so that the operator may make any necessary adjustment to the ma chine. During this interval the operator adjusts the marking device to bring the desired marking element into operative position. I11 the construction shown in the drawings this is accomplished by turning the handle 12 until the eccentric bearing-:7 is swungto its uppermost position relative to the shaft 9. The eccentricity of the bearing 7 is such that when the bearing is to be reciprocated in swung to this position the entire carrier will be elevated su'liiciently to cause the arms 5 and marking elements 13 to clear the inking pad L4. even when the reciprocating member has caused the carriage to be downwardly to the lowermost position of its stroke as shown in dotted lines in Fig. 4 of the drawings. While the carrier is in this raised position the operator selects the desired arm and marking element and rotates the carrier until this marking element is moved to the operative position, sutiicient pressure being necessary to spring the latch 1? out oi" engagement with each notch until the desired retaining notch 20 is reached. As onlx an instant is required to turn the carrier to the desired position, the handle 12 may readily be held with one hand while the carrier is moved with the other. However, a notch 22 is provided upon the ring 23 and arranged to be engaged by the latch 21 when the bearing is turned to its extreme upper position in order that the carrier may be secured in inoperative position it desired.

From the above explanation it will be noted that the marking device may be adjusted and a difierent marking element placed in operative position without stopping the machine. This is an important feature of my invention as an interruption in the operation of the machine would cause a delav throughout the entire canning process.

While I have illustrated and described what I now consider to be the preferred form of my invention it is obvious that the form and arrangement of the several parts may be modified in many ways without departing from the spirit of my invention. therefore do not wish to restrict myself to the details of construction disclosed but desire to avail myself of all modifications which may fall within the scope of the appended claims.
